Frequently Asked Questions

1. Where is the product made?
PosiFlush Saline: Columbus Nebraska
PosiFlush Heparin Lock Flush and Pre-filled Saline: Franklin, Wisconsin

2. Where are the product expiration dates shown?
Expiration dates are printed on each syringe, shelf and case label.

3. Are BD PosiFlush Syringes latex free and preservative free?
Yes

4. Can I drop BD PosiFlush Syringes onto a sterile field?
Only one BD PosiFlush Syringe is appropriate for use on a sterile field - #306553 (BD PosiFlush SF 10mL Saline Syringe). All other BD PosiFlush Saline and Heparin Lock Flush Syringes have sterile solution and fluid path, but like a traditional saline vial, the external surface is not sterile.

5. What is the syringe PSI - both when flushing and aspirating?
PSI issues in a catheter are a concern when the catheter is partially or completely occluded. In that case, static pressure builds in the catheter lumen which can damage the catheter. If the catheter is patent, pressure does not build inside the catheter. It escapes out the tip. That said, PSI generated by a syringe is determined by 2 variables, the syringe diameter and the amount of force applied to the plunger rod. 

In general, the larger the diameter of the syringe barrel, the lower the PSI generated during flushing provided the force applied to the plunger is the same. For example, in an occluded catheter, 5lb. of force applied to the plunger of a traditional 3mL syringe will generate 55 PSI. The same 5lb of force applied to a 10mL diameter syringe generates 20 PSI. When aspirating, the converse is true. Larger diameter syringes draw greater vacuum than smaller diameter syringes.
